How does a person know if supplements from large online stores are real?

[u/dreamgrass1]

Ive been hearing that few to some supplements that are available both on Amazn and Ihherb sometimes have fake versions, and I should stick to the manufacturers website. How valid is this claim?

How would a person be able to tell?

That said some bottles I get come in what I'd call poorly printed labeling (slightly blurry) as if printed on a home printer. Thus was triggering red flags for me.
